Hoosegow, a Western U.S. slang term meaning prison, comes from the Spanish juzgado, a word for court or tribunal. The OED lists one early instance of the phrase from 1911, and historical Google News searches show that the word was widespread by the ‘20s. An ngram graphing occurrence of the word in the 20th century suggests it had peaked by midcentury.
Today, writers still use hoosegow for its old-timey, colloquial ring, and it tends to appear in fiction and as a quirky affectation in other types of writing, but it’s no longer a widely used slang term.
